Title: Improvements in sewing machines having automatically operated cutting devices
IPC: D05B65/00
Filed: 1938-04-02
Abstract: 506,864. Sewing - machines. ARMSTRONG, 'J. J. V. (Union Special Maschinenfabrik Ges.) April 2, 1938, No. 10102. [Class 112] A device for cutting the chain of thread, and, if present, a reinforcing tape, connecting successive work-pieces is automatically coupled and uncoupled from driving means under the control of a feeler member engaging the work, the arrangement being such that the cutter is put into action only while the feeler member is passing through an intermediate part of its movement between extreme positions; the cutter is thus idle while there is no work in the machines as well as when sewing is in progress and is actuated to cut the chain only while the feeler member is passing on to or off the work. In the device shown diagrammatically, a fixed blade 5 co-operates with a blade 6 which is mounted on a carrier 8 pivotally mounted at 29 ; a latch 9 pivoted to the upper part of the carrier 8 has a hooked end 53 adapted to be engaged by a hooked part 54 of an arm 11, fixed on a continuously-oscillating spindle 15, to actuate the blade 6. The parts 53, 54 are normally kept out of engagement by a finger 36 on the latch 9 resting on a cam 35 fixed on the feeler carrier 25, which is also pivotally mounted at 29 and is spring-biassed and has the feeler 23 adjustably fixed to its end. A depression 35<1> in the cam 35 allows the latch 9 to fall, so that it engages the arm 11 for a few strokes, when the feeler 23 descends through the workplate 39 on passing off a work-piece 32, the depression 35<1> being such that the latch 9 is raised again to disconnect the cutter before the feeler 23 reaches the limit of its downward movement. A similar action occurs when the feeler rises on to the next work-piece.

Title: Improvements in the production of novolaks
Inventor: WHITNEY JOHN EDWARD SEAGER
IPC: C08G8/28
Filed: 1957-03-28
Abstract: Novolak resins are prepared by condensing in an aqueous medium at a pH between 4 and 7 a substantial molar excess of phenol, a m-alkyl or m-alkenyl phenol, or a mixture of phenols rich therein, with formaldehyde or a substance which acts as a source thereof to produce an aqueous solution of the corresponding methylolphenol together with unreacted phenol, dehydrating the resulting mixture under reduced pressure at a raised temperature until an exothermic reaction between the methylolphenol and the unreacted phenol sets in and then controlling the reaction without external heating by controlling the amount of water allowed to distil from the reaction mixture.  The exothermic reaction may be controlled by the alternate use of reflux and distillation.  Meta-substituted phenols specified are m-cresol, m-xylenol, m-ethyl-phenol, m-isopropylphenol and m-isopropenylphenol. Condensation catalysts mentioned for the initial reaction are the acetates, lactates, formates and benzoates of magnesium, manganese, zinc, lead, cadmium, calcium, strontium, barium and cobalt.  The phenols and catalysts used in the examples are (1) phenol itself and zinc acetate and (2) cresylic acid containing about 50% m-cresol and manganese lactate.

Abstract: 926,408. Washing-machines. CONSTRUCTA-WERKE G.m.b.H. March 16, 1962 [May 16, 1961], No. 10189/62. Class 138 (2). [Also in Group XIII] An automatic horizontal-axis rotary drum washing-machine is rotated in continually reversed senses for washing, then rotated in the sense last used in the washing period at a speed at which the centrifugal force on the washing equals its weight (so that ribs in the drum wall uniformly distribute the washing over the internal periphery), then accelerated to a spin-drying speed. The drive for the transitional period may be provided by a fixed-speed motor, or preferably an electric circuit reacts to the decrease in motor current when the centrifugal force balances the weight, to maintain the speed at the transitional value. After, e.g. 5-15 seconds, the control mechanism of the machine (or bimetallic control elements or timing relays) renders inoperative the speedlimiting circuit, and the drum accelerates.

Abstract: 884,066. Fluid actuation of switches. GENERAL ELECTRIC CO. March 24, 1960 [March 26, 1959], No. 10459/60. Class 38 (5). A switch is controlled by a piston whose face is exposed to the liquid in a yieldable chamber having one or more orifices, so that a gradual change of pressure outside the chamber has no effect upon the piston but a sudden rise of external pressure causes the piston to operate the switch. In the embodiment described, the switch housing 10 is bolted to the side 21 of an oil-filled transformer casing. A rise in pressure of the oil due to heat generated during operation or to ambient temperature changes compresses a spring-loaded bellows 60 and forces silicone oil contained therein out through orifices 28 and into an upper chamber 15 via an aperture 46. A sudden pressure increase in the transformer casing due, e.g. to arcing compresses the bellows 60 sufficiently rapidly to raise the piston 30 and operate the switch 33. The sensitivity of the device may be adjusted by means of a nut 67, and the device may be mounted if desired in communication with the gas at the top of the transformer casing.
